Position unit for positioning electromagnetic valves in fuel injection control device for two-cylinder engine of vehicle, has control unit switching control of switch units at operation rate during constant current control of valves

摘要

The position unit (20) has first switch units (22a, 22b) connected with respective low voltage terminals of electromagnetic valves (11, 12). Second switch units (23, 24) are connected with respective high voltage terminals of the valves. A control unit (21) switches control of the second switch units at an operation rate with increase in a control input of the first switch units and control of the first switch units at another operation rate with increase in a control input of the second switch units, during constant current control of the valves. The switch units are designed as MOSFETs.
